Re: OS X Yosemite

OK, total technology ignoramus here, so please be gentle...

I tried downloading the Yosemite upgrade on my 3 or 4 year old Mac Mini. Got as far as the reboot, and it has been hung up for 2 hours now. (Grey screen with the little whirling disk. No status bar, didn't even get that far.)

Normal? Not normal? Any ideas? Too early to panic? Am I screwed?

Thanks...
- get a really fast USB stick
- transfer over the install-image to that USB stick via Disk Maker X (http://liondiskmaker.com)
- do a fresh install, with wiping of the HD
- restore data from Time Machine Backup

It took a while, even on my 2.3 GHz QC i7 Mac Mini with 500 GB Crucial SSD.
It now also takes a couple of seconds longer to boot.

The Mid 2010 Mini is SATA 1, while the Mid 2011 is SATA2.
Both would benefit from the installation of an SSD, but you'd get more from it if you had the 2011' model....

Re: OS X Yosemite

Not sure if this is resolved for you yet melloncolie, but this is the advice from

http://osxdaily.com/2014/10/17/os-x-...llation-stuck/


'A notable number of Mac users who have gone to update their machines to OS X Yosemite have discovered something which may seem alarming; the progress bar seems to halt during the installation at just minutes remaining, and in some cases, it can sit unmoving with no apparent progress for well over an hour or two.


The solution to this is incredibly simple; wait it out. Even though the progress bar may get stuck on 1 minute remaining, 5 minutes remaining, 15 minutes remaining, or any other number, it may stay at that remaining number for several hours as the installation actually completes. In other words, sometimes the installation progress bar and time remaining indicator are wildly inaccurate when installing OS X Yosemite, but fortunately just being patient almost always resolves it.

If you want to watch what’s going on behind the scenes, hit Command+L to bring up the installation log. This shows exactly what’s being transferred or copied, rather than relying on the inaccurate status bar.

Another similar apparently stuck issue can also happen during the installation reboot, with the Mac being frozen on the startup screen, with the familiar Apple logo  appearing on a white or black background with a progress bar not moving. This is another situation where waiting is the best idea. And yes, it can take a while.'

Re: OS X Yosemite

So after waiting, wringing my hands, and dithering for a few more hours... the household sysadmin finally came home.

(Just what one loves to hear after a long tiring flight "Darling, there's a problem with my computer..." )

So, he said this problem had been noted by several uses on the Apple site - apparently the NVRAM needs resetting. This is what he did:

He stopped the machine using the power switch.

Restarted in safe mode, holding down the shift key while powering back on.

When it got stuck again at the halfway point, he reset the parameter NVRAM by stopping it again with the power switch and restarting holding down alt-ctrl-p-n.


(I have no idea what any of the above means.)


Anyway, that seemed to do the trick - the installation finished and I am now running Yosemite.

Thanks for the help, folks!

Re: OS X Yosemite

I installed it yesterday, took about four hours altogether (of which a whopping two and a half hours was downloading the software from the App Store). Very straightforward.

My only gripe is that I can no longer run Swiss Map Online, which was my main tool for planning hikes. And since the Federal Topographical Institute has announced that the product is being withdrawn, I guess there will be no patch to make it compatible with the new OS version.

I am getting a message telling me to install an older Java version in order to use Swiss Map (Java SE6)... is this going to break anything else if I do it?

Maybe try this:

http://support.apple.com/kb/DL1572?v...S&locale=en_US


I would make sure this version never gets run automatically and disable it as a browser-plugin.

Java6 is ancient and no longer supported.

I've got neither Java nor Flash on most of my browsers - activities that need Java are done in dedicated VMs these days.
Java has become a monster, unfortunately.
Or maybe it always was and the bugs weren't revealed for a decade...

Re: OS X Yosemite

Thanks... maybe I'll just not bother. I will need another solution next year anyway, when they pull the plug on the Swiss Map Online server.

Re: OS X Yosemite

WARNING here!


I have updated from Mavericks to Yosemite on MacBook pro late 2012 and I am having horrible screen flickering issues on certain dark/gray colors. I did not noticed it straight after upgrading as it is not visible on white background. Well, I thought that my MacBook just broke but it's not the case - I have booted from live Ubuntu and everything is fine!


I found an excellent explanation of the issue and an easy to do test:
http://www.lagom.nl/lcd-test/inversion.php#invpattern


When I am in Yosemite the 1 and 3 patterns flickers horribly. In Ubuntu they are really fine, the 2a and 4a flickers just hardly to notice rather only at the edges of the screen.


It's not the LCD panel issue, just an OS X driver issue. I do not know what to do now could it be an Apple sabotage to make people buy new Macs?
I am thinking of downgrading from TM backup - hope it will 'just work' as I am not in a mood of doing a clean install from scratch again.

Re: OS X Yosemite

so months have passed.. Is everyone happy with Yosemite? I am still with Mavericks but would feel better with a clean OS install. Having read various comments in forums on Macrumours, however, some people still seem to have WIFI problems and or performance issues. Any similar experiences?

I am rather inclined to go for clean Yosemite install assuming most people on forum are those having problems (even if they are in the minority)

A colleague of mine has spent many hours trying to sort out wifi problems on his Macbook after upgrading. He thinks he's fixed it now, but he would definitely recommend a clean install of Yosemite rather than an upgrade from Mavericks.

Re: OS X Yosemite

I've never done a clean install - bought my Macbook with Mavericks about 1.5 years ago and just do the upgrades.

I did have wifi problems, but that was after I upgraded to a later version of Mavericks. I think Yosemite is brilliant; I'm currently running 10.10.4 (public beta) and it's excellent. No issues.

Re: OS X Yosemite

I have a rather old MBP, 13inch 2011 with upgraded HDD
Apart from the screen's low resolution, I am happy with it
Just downloaded Yosemite to a USB stick, will do a clean install later this week; should be interesting to see if I have all my installation keys in place

Thanks for the replies

A few days ago, I noticed that there was an update available through the App Store on my Mac for "free" update/upgrade to OS X Yosemite.

Now, I know there's not such thing as a free lunch. There has to be a catch, a gimmick, a clause, call it what you will.

I've seen a few online comments about it, particularly comments about it crippling users wifi connections, but other than that, no real solid content.

Does anyone on here have any experience of it? What's the catch?

Follow up on my previous post. I successfully installed Yosemite, which took about 30-45 minutes from the USB and then re-install apps/transferred media back. Apart from losing the right-click functionality initially (which was fixed on Settings) I did not have any issues. Parallels is also running properly

I have not measured it but my MBP seems to be opening faster and definitely shutting down in a very short instant. So far I am very happy with the new OS and look

Terrible problem for me. Yosemite went ok, but then I upgraded to iPhoto11 and some of my photos cannot be viewed anymore. I just see them greyed out. There is some mention about this on the net but no solution yet. Something to do with files and permissions or something.

always back-up before doing any upgrade with MacOS. You can always recover with time machine at some point.
